You souldn't have problems as you have the recomended HW.
When I decided to get the Crossfire, I read that it works with all
applications etc... I am really sorry I never went for the ATI FIREGL though...

I found a way for me to render in hardware without getting any artifacting. I use the hardware buffer render, but unfortunatly it does not support saving etc... :headbang:
If they release Maya PLE 8 then I will have a look to see if it works with my card there first before I make any decisions...
